The article considers the issues of aquatic macrophytes’ resistance to environmental pollution. Results of model investigations aimed at revealing of alterations in photosynthetic pigments’ content in Elodea canadensis in the presence of heavy metals (nickel as an example) in the concentration gradient have been presented. Comparison of individual pollutants’ and their combinations’ action upon structural parameters of E. densa leaf has been done. It has been shown that the plants under investigation possess high adaptive potential and the ability to resist pollutants action due to alterations of structural/functional characteristics of the photosynthetic apparatus.
